An Aggregation-based QoS Architecture for Network Mobility

In recent years, extensive studies have been undertaken in order to provide Quality of Service (QoS) for individual mobile nodes in wireless networks. With the development of Network Mobility (NEMO) technology, the provision of QoS for moving networks based on NEMO is emerging as a new research area. However, it is very difficult to directly apply existing QoS technologies to NEMO because of the unique characteristics of such networks. This paper proposes a novel two-level aggregation-based QoS architecture to guarantee QoS for moving networks based on NEMO. In this architecture, flow aggregation and dynamic SLS negotiation are applied at the two levels. Furthermore, a universal signalling protocol is being designed to meet the QoS requirement of NEMO. This signaling protocol can transfer the control information not only between the two levels in the NEMO network but also between the NEMO network and the visited network domain.
